DETAILED DESCRIPTION OF EMBODIMENTS

For purposes of description herein the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the device as oriented in FIG. 1. However, it is to be understood that the device may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

Referring to the embodiment illustrated in FIG. 1, reference numeral 10 generally designates a refrigerator or refrigerator column. The refrigerator 10 includes a cabinet 15 in which at least one internal refrigerated compartment 20 is provided. At least one door 17 is provided for each internal refrigerated compartment 20 to selectively seal the compartment 20 or allow for a user to access the compartment 20. Each internal refrigerated compartment 20 may have a plurality of refrigeration zones 22, 24, and 26 for which the environment in each refrigeration zone may be independently controlled using a user interface 40 configured to receive a zone selection input 42, 44, and 46 from a user indicating at least one of the plurality of refrigeration zones 22, 24, and 26 in which the user desires to adjust the environment.

Refrigerator 10 may further include a plurality of lights provided in the internal refrigerated compartment 20 and disposed proximate each of the refrigeration zones 22, 24, and 26, wherein groups 32, 34, and 36 of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones 22, 24, and 26, respectively.

In addition, refrigerator may include a controller 100 (FIG. 2) coupled to the groups 32, 34, and 36 of the plurality of lights and in communication with the user interface 40. The controller may be configured to receive a zone selection input from the user interface 40; identify a group (32, 34, 36) of the plurality of lights that are disposed proximate the selected refrigeration zone(s) (22, 24, 26); and control the identified group (32, 34, 36) of the plurality of lights in a manner so as to visually confirm the selected refrigeration zone(s) (22, 24, 26).

In the particular example shown in the drawings, the internal refrigerated compartment 20 includes a first refrigeration zone 22, a second refrigeration zone 24, and a third refrigeration zone 26. First refrigeration zone 22 is located at the top of the internal refrigerated compartment 20 and is the largest zone in the refrigerator 10 and includes a plurality of shelves 23 that are generally used for storing an assortment of food products. Second refrigeration zone 24 is located at the middle of the internal refrigerated compartment 20 and includes a tray 25. Second zone 24 may be designated for use as either storage for deli products or produce. Third refrigeration zone 26 is located at the bottom of the internal refrigerated compartment 20 and includes crisper drawers 27. Third zone 26 may similarly be designated for use as either storage for deli products or produce.

Although three refrigeration zones 22, 24, and 26 are shown and described, the internal refrigerated compartment 20 may include any number of such zones. Moreover, the refrigeration zones may have different functions, uses, and arrangements than those shown and described herein. Further, although refrigerator 10 is shown with only one internal refrigerated compartment 20, it may have additional compartments, which may have their own respective doors 17. For example, refrigerator 10 may have a second internal refrigerated compartment for use as a freezer. In addition, the internal refrigerated compartment 20 shown may be used as a freezer. As used herein the term “refrigerator” shall mean any refrigerated appliance including not just refrigerators, but also freezers, combination refrigerators/freezers as well as refrigerated vending machines and refrigerated display cases. Further, although shown as an upright refrigerator, the refrigerator may be in the form of a chest or a walk-in refrigerator/freezer. Additionally, the refrigerator may be used for storing not only food products, but also any item that may be desired to be refrigerated or frozen. Lastly, the refrigerator 10 may be a home refrigerator, a commercial refrigerator, or a lab refrigerator.

As shown in the drawings, a first group of lights 32 is provided around the top and both sides of the perimeter of the first refrigeration zone 22, a second group of lights 34 is provided along both sides of the perimeter of the second refrigeration zone 24, and a third group of lights 36 is provided along both sides of the perimeter of the third refrigeration zone 26. In this manner, each group of lights 32, 34, and 36 identifies the boundaries of the associated refrigeration zone 22, 24, and 26.

Although the light groups 32, 34, and 36 are shown in the drawings as extending around the perimeter of the opening of the internal refrigerated compartment 20, the light groups may be disposed in any location and in any manner so as to provide visual confirmation of the refrigeration zone that is selected by the user. Although not necessary, it is desirable to have the light groups disposed in such a way as to visually indicate the boundaries of the respective refrigeration zones.

The refrigerator 10 may further include various shelves 23, trays 25, and drawers 27. Some of shelves 23, trays 25, and drawers 27 may separate one refrigerated zone from another. Although not shown in the drawings, one or more of the shelves 23, trays 25, and drawers 27 may have lights or a light pipe integrated along their outer edge as disclosed in commonly-assigned U.S. Patent Application Publication No. 2014/0268862 A1, the entire disclosure of which is incorporated by reference. Such edge lighting may be included in a group of lights (32, 34, and 36) to help identify the selected refrigeration zone (22, 24, and 26).

As also shown in FIG. 1, user interface 40 may include a zone selection input that allows the user to select one or more particular refrigeration zones for which the user may wish to adjust the environment. In the example shown, three separate zone selection inputs 42, 44, and 46 are shown with one input for each respective refrigeration zone 22, 24, and 26. As shown, user interface 40 is provided in the form of a touch screen display on which the three separate zone selection inputs 42, 44, and 46 are represented by three graphic icons that each graphically represents a different one of the three refrigeration zones 22, 24, and 26, respectively. The user interface 40 may further include inputs 48 for adjusting a parameter used to control the environment in the selected refrigeration zone(s). As described further below, these inputs 48 may be reconfigurable to show only those parameters that may be adjusted for the refrigeration zone(s) that is selected. The user interface 40 may also include a home input 41 used to activate the user interface 40 and/or return to a home screen. Further, additional inputs 49 may be provided for controlling the refrigerator. Inputs on the touch screen display serving as user interface 40 may be activated simply by touching a displayed icon wherein the touch may be sensed using capacitive sense switching. It should be noted that the user may select only one zone to control at a time or may select multiple zones for which a parameter is to be adjusted.

Although the user interface 40 is shown and described as a reconfigurable touch screen display, it may also be a fixed touch screen display or any other form of display. Further, user interface 40 may take any other form including a set of dedicated user input push buttons with or without indicator lights and backlighting. Moreover, although separate zone inputs 42, 44, and 46 are provided for each zone, a single zone selection input may be provided that toggles between the respective zones wherein the selected zone may or may not be displayed on the user interface 40. Additionally, the user interface 40 may be located inside or outside of the refrigerator 10. In the event it is located on the outside of the refrigerator, it may be advantageous to provide glass windows in the doors 17 such that the user may be able to see the interior compartment 20 and therefore see the visual confirmation of the zone selection provided by the interior lighting. Further, as described below, user interface 40 may be provided in a location remote from the refrigerator 10, such as within a smartphone 50 (FIGS. 2 and 5) or any other remote control device.

FIG. 2 shows a block diagram of an electrical circuit for implementing the lighting scheme in the refrigerator 10 shown in FIG. 1. As shown, the circuit includes a controller 100 that is connected to the user interface 40 so as to receive zone selection inputs as well as other inputs such as parameter adjustment input to adjust a parameter for adjusting the environment of the selected refrigeration zone. Controller 100 may also be configured to control the display of user interface 40. The controller 100 is also coupled to the first group of lights 32, the second group of lights 34, and the third group of lights 36 for controlling the lighting generated by such light groups. For example, the controller 100 may independently activate and deactivate the groups of lights, change their intensity, modulate their intensity, and/or change their color. The lights in the light groups may be LEDs, which may have a single color or may be multi-color.

The controller 100 may also be coupled to the refrigeration control system 102, or be an integral part thereof, for carrying out the adjustments to the environments of the respective refrigeration zones 22, 24, and 26 as instructed through the user interface 40. The controller 100 may include a single processor or a plurality of processors distributed within the refrigerator and thus the functions described below may be performed by one processor or by two or more processors.

The controller 100 may also be coupled to one or more door switches 112, which signal when a door 17 is open.

Further, the electrical circuit may include a wireless interface 104 coupled to the controller 100 for allowing wireless communication with a remote user interface 50, which may be in the form of a remote control or a smartphone, tablet, laptop or desktop computer. The wireless interface 104 may provide for wireless communication using one or several communications protocols. For example, the wireless interface 104 may communicate directly with remote user interface 50 via IR or RF signals and may use a protocol such as BLUETOOTH or the like. Alternatively, the wireless interface 104 may communicate indirectly with remote user interface 50 via a Wi-Fi router 106 or via the Internet 110.

Having described the structural components of the refrigerator 10, a method of controlling interior lights of the refrigerator 10 will now be described with respect to FIG. 3. The method is described herein as being implemented by the controller 100 and may be stored in a memory associated with the controller 100 as a subroutine executed by the controller 100 (or more specifically, one or more processors of the controller 100 and/or refrigeration control system 102). The method may be embodied as a non-transitory computer readable medium having stored thereon software instructions that, when executed by the controller 100, cause the controller 100 to execute the steps of the method. In other words, aspects of the method may be achieved by software stored on a non-transitory computer readable medium or software modifications or updates to existing software residing in a non-transitory computer readable medium. Such software or software updates may be downloaded into a first non-transitory computer readable medium of the controller 100, typically prior to being installed in the refrigerator 10, from a second non-transitory computer readable medium remotely located from the first non-transitory computer readable medium associated with the controller 100. The second non-transitory computer readable medium may be in communication with the first non-transitory computer readable medium by any suitable means, which may at least partially include the Internet or a local or wide area wired or wireless network.

As shown in FIG. 3, the method may begin at step 120, where the controller 100 determines if a door 17 is open based on a signal received from the door switch(es). Once a door 17 is open, the controller 100 may turn on all the interior light groups (groups 32, 34, and 36) in a normal lighting condition such that the user may readily see the items in the interior refrigerated compartment 20 (step 122). Then, in step 124, the controller 100 determines if the user interface 40 (or the remote user interface 50) has been activated. As noted above, this may be done by touching the user interface 40 on the home icon 41 or optionally anywhere on the touchscreen display serving as the user interface 40. If the user interface 40 has been activated (or if already active, if a zone is selected using icon 42, 44, or 46), the controller 100 receives any zone selection input from the user interface 40 in step 126. Next, in step 128, the controller 100 identifies which group of lights 32, 34, or 36 is associated with the selected refrigeration zone 22, 24, or 26. The controller 100 then controls the identified group of lights in such a manner as to visually distinguish the selected zone from the other zones in step 130.

As noted above, this may be by modulating the intensity of the light group associated with the selected zone, or by changing the color and/or brightness. One effective way in which to modulate the intensity of the group of lights is to slowly fade their intensity and then slowly bring their intensity back (which may be repeated several times). This gives the impression of breathing which emotes that the user has brought that zone to life. Further, the lighting of the associated zone selection icon 42, 44, 46 may be faded in intensity in the same manner and in synchronization with the fading in intensity of the group of lights 32, 34, 36 associated with the selected zone 22, 24, 26.

In step 134, the controller 100 receives any user adjustments of any parameters (via inputs 48) to change the environment of the selected refrigeration zone. In this regard, the controller 100 may cause the display on the user interface 40 to change so that only inputs 48 for those parameters that are relevant to the selected zone may be displayed. For example, as shown in FIG. 4A, when a user presses first zone selection icon 42, the icon is illuminated in a pulsing manner (or in a brighter manner or a different color) similar to the pulsing of the first group of lights 32 of the corresponding first refrigeration zone 22 that is selected. The user interface 40 then displays for inputs 48, the temperature at which the first refrigeration zone 22 is set along with inputs for adjusting the temperature up or down or for selecting Fahrenheit or Celsius. Similarly, inputs 49 may include “Max Cool,” “Reset Filter*,” “Vacation,” “Sabbath” and “Lock*.” On the other hand, if the user selects the second zone selection icon 44, the icon lighting is changed and the lighting of the second light group 34 is changed to confirm the user's selection of the second refrigeration zone 24 as shown in FIG. 4B. The user interface 40 then displays for inputs 48, a number of possible functions/uses for the second refrigeration zone 24, such as “Assorted,” “Deli,” “Produce,” “Beverage,” “Meat” or “Quick Chill.” Selection of any one of these functions/uses may change the temperature setting for the second refrigeration zone 24 as well as the humidity level and possibly other environmental conditions. Similarly, inputs 49 may remain unchanged. If the user selects the third zone selection icon 46, the icon lighting is changed and the lighting of the third light group 36 is changed to confirm the user's selection of the third refrigeration zone 24 as shown in FIG. 4C. The user interface 40 then displays for inputs 48, a number of possible functions/uses for the third refrigeration zone 26, such as “Assorted” and “Produce.” Note that the parameters need not be limited to any of the above parameters and the same or different parameters may be displayed for any or all zones.

Referring back to FIG. 3, in step 136, in response to any adjustment of a parameter via inputs 48, controller 100 takes whatever action is necessary to effect that adjustment whether it does so directly or indirectly by signaling the refrigeration control system 102. Then in step 138, once the action is completed, the controller 100 returns the light group for the selected refrigeration zone back to the normal lighting condition. If a zone is selected again, the controller 100 will repeat steps 126-136 for the selected zone.

After step 138 or if the controller 100 determines in step 124 that the user interface 40 has not been activated or touched, the controller 100 will check to see if the door 17 has been closed in step 140. If not the lights will remain on in their normal lighting condition. If the door is closed, the controller will turn off the interior light groups. Note that if any door includes a window, some or all the lights may remain on with the door closed either indefinitely or for a predetermined time.

FIG. 5 shows a refrigeration system 5 including two column refrigerators 10 and 10 a arranged side by side. Note that the refrigerator column 10 is the same as the refrigerator shown above and refrigerator column 10 a is similar in all respects except that it may or may not have its own user interface 40 (and possibly not its own controller 100). Accordingly, the similar parts of refrigerator column 10 a share the same reference numerals with an appended “a.” The purpose of showing this refrigeration system 5 is to demonstrate that a single user interface 40 (or remote user interface 50) may be used to control two separate refrigerator columns 10 and 10 a if desired.

The lighting method described above may be used in other appliances in which it is useful to provide visual confirmation of one of a plurality of different zones. For example, the above described lighting scheme may be used in solid-state microwave cooking appliances in which there may be different cooking zones where food may be cooked differently than food in another zone. An example of such a cooking appliance is described in commonly-assigned U.S. Pat. No. 6,884,979, the entire disclosure of which is incorporated by reference.
